DOOR-CHECK SPECIFICATION forming part of Letters Patent No. 371,999,dated October 2'5, 1887.k

Application tiled January 3, 1887. Serial No. 223,265. (Model.)

To all whom it may concern,.-

Beit known that I, GHARLEs A. WILLIAMs, ofThirty-sixth ward, Pittsburg,Pennsylvania, have invented a new and useful Improvement in LockingDevices for Doors,which improvement is fully set forth in the followingspecifi cation, reference being had to the accompanying drawings.

Similar letters of reference indicate corresponding parts.

My invention relates to a device for locking or bracing doors when openor partly open, and the same device can be used as a bumper, all ofwhich will be more fully set forth hereinafter.

ln the accompanying drawings, Figure l shows my door-locking device whenin position or attached to a door, the dotted lines in horizontalposition showing the device in position to be used as a bumper. Thevertical dotted lines show the same when thrown up Fig. 2 is asectionalview.

A represents a section of a door.

B is the base of my device, and has holes a c' for screws. To this baseB are thelugs d d, through which is a bolt-hole, b5, attached.

C is a bar which is secured to the lugs d d by a bolt through theopening in d. This bar terminates in a rod, c, and has a threaded end tofit in the nut b2, inside the movable tip b. By this means the tip b isheld in the sleeve B' and against the spring c c'.

b is a rubber cushion secured to the tip b.

Instead of using a bolt at d', I may secure the bar C to the lugs cl byputting trun nions b on the bar C, and then have slots b4 in the lugs d,either partly or entirely through the same. The sleeve B is hollow partway into the same to admit the spring c/ and tip b. The balance of thesleeve B has a hole of a size barely sufiicicnt to admit the bar C.

The

spring c' rests against the bore of the sleeve B and against the tip b,and by this means the sleeve can be drawn out sufficiently to put thelocking devioein the several positions aforesaid by having the inne-rend of said sleeve engage the lugs.

When my locking device is intended to brace a door open, for instance,the tip is placed against the floor, as seen in Fig. l, slightlyinclinedfrom the door. The tip being on a spring, is made adjustable on floorsthat are uneven. y

When not otherwise used, my device can readily be madeinto a bumper, asseen in Fig. 1 in the horizontal dotted lines, before referred toa Vhenthe bar C is secured by trunnions, as aforesaid, there Will be a squareopening made in the base B, (marked B2 in Fig. 2,) and then the bar willbe passed up through such opening and the trunnions bi will go into theslots b4 and may revolve therein, the same as ou a bolt.

Having thus described my invention,\vhat I claim, and desire to secureby Letters Patent, 1s-

As an improved article of manufacture, a door-check consisting of abracket havinglugjournals, a bar pivoted therein, a movable clip on theouter end of the said bar, a movable sleeve, and a spring having one endbearing against the sleeve and the opposite end bearing against theclip, substantially as specified.

In testimony that I claim the foregoing as my invention I hereto set myhand in presence of two witnesses.

CHARLES A. VILLIAMS.
